Expectations formation: Rational or adaptive or …?
Journal of Economic Behavior & Organization, 1994Abstract This paper reports on an experimental investigation in which subjects are appropriately motivated to reveal their expectations of two time series. Two hypotheses are investigated: that expectations are formed rationally; that they are formed adaptively.

Thioether Formation — Activation or Detoxication?
1989During biotransformation of aromatic amines, activated phase I metabolites, like aminophenols, occasionally escape the liver and exert toxic effects in sensitive target organs, e.g. the kidneys. The first organ in contact with these proximate toxic compounds is the blood, however.

Models of coalition or alliance formation
Journal of Theoretical Biology, 2011More than half a century has now elapsed since coalition or alliance formation theory (CAFT) was first developed. During that time, researchers have amassed a vast amount of detailed and high-quality data on coalitions or alliances among primates and other animals. But models have not kept pace, and more relevant theory is needed.

Moscow University Geology Bulletin, 2008
The physics of the ore formation process is discussed using three parageneses of gold, viz., quartz, carbon, and pyrite, as examples. It is inferred that paragenetic associations in ore deposits are formed on a physical basis under the influence of magnetic fields of nuclides and electrons.

Geology of Ore Deposits, 2008
Ore formation is considered in the paper. The consideration is based on the topology of chemical elements that was discovered by the authors in 2007 as a result of the study of the Fibonacci distribution of chemical elements. On thoroughly analyzing the physical background of ore formation, we have concluded that spin effects play the leading role in ...

Magnesian-Magnetite Ore Formation
1988Abstract Iron mineralization is widely developed within the Angaro-Vilujsky ore belt [2]. In the Noril’sk region, it is found along the western border of the Tungussky syncline and also within the Noril’sk-Kharayelakh depression. The Angaro-Noril’sk metallogenic zone contains some iron mineralization (as deined by N. V.

Abstract Porphyry copper mineralization in the Noril’sk region is an unusual example of the occurrence of this ore type within an ancient platform. Such a spatial setting of these deposits makes one cautious in interpreting the tectonic regime of the boundary portion of the platform, because the majority of porphyry., copper deposits are

Abstract The first evidence of native copper in the volcanic rocks in the northern part of the Siberian platform was published in the classic work of V.I. Vernadsky “An Opus on Descriptive Mineralogy”. In 1945, G.G. Moor, while analyzing scarce data on native copper in the lava fields of the area of the Siberian traps concluded that ...

DEFECTS OF ORE FORMATION ANALYSIS
Geology and mineral resources of Siberia, 2021The typification of solid mineral deposits is a leading element in the forecast of mineralization. By analogy with magmatic formations, it is based on the ore formation analysis. However, due to the absence of discrete boundaries between formations, their diagnostics encounters insurmountable difficulties, and the classification becomes dubious and ...

Karharbari: a formation or biozone
Journal of Palaeosciences, 1987In the initial identification of the Karharbari sediment in Giridih Coalfield both litho- and bio- characters of the sediments were emphasized. Later, Karharbari has been considered as lithologically distinct unit, a definite palaeontological zone and both combined as a chronostratigraphic unit in between Talchir and Barakar.
